1l '0 all whom t may concern:

Be it known that we, JAMES R. MoFrA'rT and RALPH S. KnLso, citizens of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, ofvwhich the following is afdescription, reference being had to the accompanying drawing and to the letters i0 and figures of reference marked thereon.

The invention relates to new and useful improvements in sewing machines, and more especially sewing machines foil stitching a folded fabric to a body fabric.

An object of the invention is to provide devices for feeding and applying a length of tape to a fabric being stitched, at a point in advance of the stitching mechanism.

A further object of the invention is to provide means` for cutting lengths of tape, applying one end thereof to a fabric and tucking or folding the end of the tape underneath the folded edge of thel fabric and at a point in advance of the stitching mechanism.

A further object of the invention is to provide means for feeding lengths of tape and applying the same to a fabric being stitched, and to provide means for varying :i the lengths of the tape being supplied.

These' and other objects will in part be obvious, and will in part be hereinafter more fully described.

View similar to Fig. 2, showing a modified form of, operat- 9E ing mechanism for the folding finger.

7e-have shown our invention as applied to a sewing machine which is equipped with a rufliing ing a body strip device for rulil and av folder for folding the edge of the overhanging arm 2, carrying a needle head which is mounted on a feed 3 at its forward end. A needle bar 4 reciprocates in the needle head, and is preferably. provided with two needles and 6. A presser bar is also mounted in the needle head and carries a presser foot .7, which may be of the ordinary construction.' The presser foot, as herein shown is, however, provided with a slot 8 at its forward end, as shown in Fig. 5. The feeding mechanism is f the usual character and consists of a feed dog I" bar and moved back and forth and up and down.

The ruliling blade 9 (see Fig. 3), is carried by a rufliing head l0, mounted on a sliding bar 11 carried by bearings formed in the bracket mounted on the needle head. The bar 11 is reciprocated through a link connection with a rock lever 12. A lever 13 is provided for swinging the ruffler head and lifting the rutlling blade from the material when said rufiling blade is rendered inactive by mechanism controlled by the operator. character shown in the Woodward Patent No. 655,143, dated July 31st, 1900, and will not need further description in this con nection.

Mounted on the work support 1 is a folder 14. Said folder consists of a base portion 15, a laterally projecting raised portion 1G, which is spaced from the work support to form the guiding groove i 17 for a body fabric A. Mounted on the raised portion 16 is a stripper blade 18, over which the fabric B to be ruffled extends, and the edge of the fabric is guided by a groove 19 formed in the folder 15. The third strip of fabric C is led through the folder and the edge thereof is turned by the guiding passage 2() in the folder. The lower wall of the folder 14 extends forwardly and laterally and is slightly bent upwardly to form a curved ledge 21 (see Fig. The intermediate wall of the folder extends forwardly to form a supporting finger or wall 22, the purpose of which will be hereinafter more fully described.

The rullling blade 9 is provided with a laterally extending part 23 (see Figs. 8 and 9), and also with an extension 24, which forms a continuation of the wall or finger 22 when the rufl'ling blade is at the forward v'end of the stroke, as shown in Fig. S.

ln the operation of the above devices` the strip of fabric C is led through the folder 14. with its edge folded underneath and positioned directly above the body fabrics plied and properly This ruillingmecbanism is of the A and B. The ruliler blade engages the fabric B at a point underneath the lower wall of the folder 11, andpressing the same against the stripper blade 18, will rutile the same. It will thus be seen that the intermediate fabric B may be ruffled at times, if desired, without in any Way interfering with the free feeding ofthe folded strip C, or the body fabric A.

It is found-desirable in certain classes of work, to attach short lengths of tape to fabries folded and stitched, as above described, which lengths of tape extend in a direction at right angles to the line of seam, and one end of the tape is folded about the folded edge of the strip of fabric C. In order that a tape of this character may be quickly appositioned relative to the fabrics at a point in front of the stitching mechanism, we have provided manually controlled means for feeding and applying the tape. Said manually controlled tapeapplying means consists generally of a tape carrier, a cutting mechanism for cutting the -measured lengths of tape, a folding or tucking frame 25 is formed with ears 29, which are pivotally supported on the rod 28. The purpose of the swinging frame 25 is to allow the various parts of the tape-inani}nilating device to be swung away from the needle, so as to give access to the looper of the sewf ing machine or other parts adjacent the stitching mechanism. The swinging frame carries an arm 80, which is held by a spring finger 31 when the frame is swung upward to the position shown in l `ig.^3.

Tay/c crrcr. The tape carrier consists of a guiding member 32 which is preferably rectangular in cross section, and is formed with an opening 33 in its upper wall (see Figs. 11 and 12). A pawl 34 extends through the opening 33 and rests against the tape which freely passes through the tape guide 32. This pawl 34 will allow the tape to move freely in one direction through the tape guide, or the tape guide to slide on the tape in the direction of the arrow, Fig. 12,

carried along with the guide. This tape ide 32 is mounted on an arm 35, which is pivoted at 26 to the swinging frame 25.y As a means for moving the tape carrier, We have provided an operating lever 37, which is also pivoted at 36 to the swinging frame. This operating lever 37 is formed, as herein shown, with a erating lever may be readily swung. The arm 35 on which the tape carrier is mounted, is provided with a block 39 having a V- shaped notch, (see Fig. 21). The operating' vlever 37 has a spring 40, rigidly connected thereto, which spring at its outer end engages the V-shaped notch in the block 39. The arm 35 through this spring connection will movewith the operating lever 37. ,The spring connection, however, will allow a further movement of the operating lever; 2Q, for the purposes hereinafter described. i

Cutting meoham'amadThe cutting mechanismfor cutting'y theilengths of tape, consists of two cutting blades 41 and 42 (see Figs. 1() and 19). The swinging frame 25 25 is provided with a downwardly projecting arm 43, which is formed with a head 44, in which the movable cutting blade 41 slides. The blade' 42 is fixed to the lower face of the head by suitable screws, as shown in Fig.` 10. The blade 41 is held in the `guiding channel in the head by a fixed finger 43, -and .a yielding finger 44, which presses against the blade so as to prevent false |movements thereof. A screw 45 limits the movement of the blade.

The movable blade 41 is formed with thel usual guiding finger 46, which maintains the roper coperatlve relation between the lades. Said movable blade is reciprocated 40 back and forth by a rock lever 47, which is pivoted at 48 to the swinging frame 25. Said rock lever carries an arm 49, which is formed with spaced fingers 50 and51, at its outer end, and a recess 52.

The operating lever 37 carries a projecting 'arm 53 which is provided with a roller 54. When the operating lever is swung outwardly, or upwardly, vthe roller 54 will pass between the guiding fingers 50 and 51, -into the recess 52, and a further u )ward movement of the operating lever 3 will swing the rock lever 47 and reciprocate the movable blade 41, so as to eut the tape.

A stop 55 is mounted on the swinging frame 25, and said stop lies in the path of movement of the tape carrier, so that when the tape carrier is moved outwardly and upwardly, it will engage the stop 55and a further upward movement of the tape carrier be prevented. The operating level' 37, owing to the spring connection with the tape carrier may be moved still farther upward, and thus operate the cutting blades to sever the tape, while the tape carrier is held stationary. This stop-55 is adjustable, and by handle 38, by which the opvarying the position of the same, the distance of movement of the tape carrier above the cutting blades, before reaching a position of rest, may be varied, and thus the amount of tape projecting beyond the end of the tape carrier also varied, for the purvpose hereinafter described.

'The finger 56 is rigidly attached to lThe rock lever The folding fingern-When the tape carrier is moved in the direction of the arrow, Fig. 2, a length of tape will be carried down to a position adjacent the folder 14 of the sewing machine, and the end of the tape will project beyond the tape carrier, as above described. Inox-'der to fold this projecting end of tape underneath the folded ends of the fabric, we have provided a folding or tucking finger 56. rThis folding finger 56, as clearly shown in Figs. 2 and 14, is bent outwardly, then downwardly and then laterally, so as to form a curved finger with a substantially horizontally projecting part. a bar 57, which is pivoted at 58 to a rock lever 59. 59 is in turn pivoted to the swinging frame 25.

Tn order to properlyfold the tape underneath the edge of the fabric, it is necessary to swing the folding finger first outwardly, then downwardly and then inwardly, to carry the same about the supporting ledge for the folded fabric. 4These movements are imparted to the folding finger through a cam plate 60. Said cam plate 60 is mounted 4to slide vertically on the swinging frame 25, and is guided by two 10e studs 61, which engage vertical grooves 62 in the cam plate 60. The upper vertical a slot 62 is formed with a cam slot 63, which engages a pin 64 carried by Ithe rock lever 59. The cam plate 60 is provided with a 105 second cam groove 164, which engages a pin 65, carried by the bar 57.,

When the folding finger is in its extreme upper or inoperative position, the plate 60 is at the upward end of its stroke, as shown 11o in Fig. 1. Adownward movement of the plate will cause the piu' 64 to move to theA right, as viewed in 4ig. 1, thus swinging the rock lever 59, which will carry the folding finger downwardly. As the rock lever 115 moves downwardly, the pin 65 will also move downwardly with the same, and thus the har 57 will be moved substantially in the direction of its length. As soon as the pin 64 reaches the vertical portion of the 12o slot in the plate 60, the rock lever will cease its swinging movement, and the cam slot 164 will movll the pin 65 to the left, as viewed in Fig. 1, andthus swing the folding fiugeri5(' to the'right, underneath 125 the supporting ledge and carry the end of the tape underneath this ledge.

As a means for moving the cam plate 60, we have provided a yoke 66, which is formed with two' arms 67 and 68. The arm 13o Q0 end of the I 67 carries projecting fingers 69, which engage a roller on the plate 60. The yoke (56 is pivoted at 71 to the swinging frame 25.

The operating lever 37 is formed with a bracket arm 72, which is preferably adjustably attached to said lever. This bracket projects laterallyand then rearwardly and again laterally, and carries a roller 73,

'which is substantially in line With the central axis of the operating lever. The object of the laterally deflected bracket 72 is to provide for a free movement of the lever, relative to the tape carrier, and to position the roller 73 in the rear of the arm on which the tape carrier is mounted. The arm 68 is so disposed relative tothe roller 73, that when'the tape carrier is moved to the position shown in Fig. 1 and the operating lever' 37 is given a further movement to operate the cutter, said roller 73 will engage said arm (i8, swing the yoke (i6 and lift the cam plate 60. When the tape carrier is moved in the opposite direction by the oper` ating lever 37, the arm 35 will strike an adjustable stop 74, and thus arrest the for- Ward movement of the tape carrier. The operating lever 37 may be moved still farther to the left, in view of the yielding connection with the tape carrier. The arm 67 is so disposed relative to the roller 73, that when the lever 37 is given the further additional movement above referred to, said arm will be engaged by the roller, and the plate 60 lowered. The plate 60 may be held in its various positions by any desired means.,

The auxiliary 772025.*111 order to properly hold the tape with its end folded about the edge of the fabric, we have'provided an auxiliary foot 75, (see'Figs. 5 and 18). This auxiliary ,footf75 is formed on its under face with a curved surface 76. Said foot is located directly over the supporting finger or ledge 22, (see Figs. 5 and 8). The foot is carried by a bar 77, which slides in a guiding channel in the bracket A spring 78 normallv presses said foot downwardly. A lever 79 engages a pin .80 on the har 77 and by swinging the lever, the auxiliary foot 75 may be raised.

The auxiliary foot is also provided. with a. laterally extending arm 81. The rear end et the foot extendsA into the slot 8 in the presser foot, and the arm 81 extends over the presser foot. so that when said presser foot is raised in the usual wav. the auxiliary foot 7:3 will also be raised. This allows for the lifting of the foot when the material is to be inserted into the machine.

ln order to lift the auxiliary foot so that the tape may be placed underneath the same, we have. formed the arm 35 which supports the tape carrier, with a projecting member 82, which carries a roller 83, (see Fig. 13). The lever 79 is so disposed der that different that when the tapel carrier is swung in the direction of the arrow,- (Fig. 2), the roller 83 will engage the lever 79, raise the wir:n iliary foot and hold the same raised, that the tape may be passed underneath the auxiliary foot. When the tape carrier is swung in the opposite direction, the auxiliary foot will be released, and the spring 78 will move the same into contact with the tape, and properly hold said tape, whereby it may be fed with the fabrics being stitched to the stitching mechanism.

The endl-of for ze taper-F rom the above description, it will be noted that the distance between the folder or line of feed ln'orlengths of tapes may be we have provided a pullo' which consists of ay tape-engaging finger 84. This tape-engaging finger 8a; is earried by an arm 85, pivoted at 71 to the .swinging frame it.. second arm wiil. swing the arm 85.

Mounted on the arm is a. roller 87. The arm y8G is so disposed that the roller 87 will engage the lower face thereof when the arm 35 is moved in to the arrow in Fig. 2. ally deflected, so as to allow this roller to pass by the arm and engage the arm 86.

"When the tape carrier is moved along the tape to measure oit the length of tape, the pull-ofi' finger 8e will be carried into engagement with the tape, as shown in. Fig. l.. and by'laterally.defecting the tape, Y increase or decrease thn len 5th of tape to be out, according to the position oi the pulloil finger 84. This iinger 84 is adjustabiy carried by the arm 85, and thereby the length of tape will be readily varied.

@pf/mtime of the mpc-applying deviner- The parts are normally in the position shown in Fig. 1, except the tape is cut and allowed to drop. so that it may be stitched to the fabric. ln this position a portion of the tape projects beyond the tape carrier 32, the length of this projecting portion being Varied by adjusting the stop 55, so as to determine the throw of the carrier above the cutters.

When it is desired to apply a tape to the material being stitched,'the handle 38 is grasped and the carrier swung downward in the direction of the arrow in Fig. 2. The tape will beca-rried along with the carrier, the roller 83 will engage the' lever 79 and lift the auxiliary presser foot. so that the tape and carrier may move underneath the same, as shown in Fig. 23. The tape carrier now engages the stop 74, and a further movement thereof is prevented. lin this position, the tape projects beyond the edge' of the folded fabric, and the supporting ledge therefor, as shown in Fig. 23. further movement of the operating lever 'will and the cutting device, is constant.

will be released, and the auxiliary foot lwill be lowered, through the action of the spring,

on to the tape and hold the same in proper position against the upperface of the folded strip of fabric.

As the tape carrier moves outward and upwardly, the pull-off finger'will be brought into engagement with the tape and deflect the same. so as to determine the lengthof tape which is to be severed. llVhen the carrier strikes the stop 75, a further upward movement of the operating lever 37 will sever the tape.

' By adjusting the stop 71 we are able to vary the position of the carrier relative to the folding finger, and thus adjust the distance -which the tape extending beyondl the tape carrier may be passed tothe right of the top fold of the material or fabric which is to be stitched. By adjusting the stop 55 we may adjust the distance which the tape extends beyond the tape carrier, and thus provide a means for varying the amount of tape which is folded around the edge of the folded fabric.

ln Fig. 26, we have shown a modified form of means for moving the operating lever. In this figure. the operating lever is shown as provided with a second arm 88, which is rigidly connected to the operating lever 37. This arm 88 is connecte to a rock lever 89 by an adjustable link 90. The rock lever 89 is connected by a chain .or other flexible connection 91, to a suitable. treadle. A spring 92 may be provided for normally holding the treadle` raised and the operating lever 37 in the position shown in Fig. 1.

' lVhile we have shown our device as appliedI to a machine equipped with a rufllcr and with a folder, it is obvious from certain aspects of the invention. that the tapefeeding and applying devices may be used in connection with other types of sewing machines, or in any place where it is desired to supply lengths of tape or the equivalent thereof. It is also obvious that various changes in the arrangement of parts` and the details of construction may be made, without departing from the spirit of our invention, as set forth in the appended claims.
